i have a 97 mesa dual rec 2 channel. tonite it started "whistling", only stopping when the stand by is on. when i changed the rectifier setting from diode to tubes, it reduces the sound significantly but it is still slightly there. it's almost like a kettle whistle but not quite as high pitched. at first i thought it might be a tiny tear in one of my speakers. either way baby both the head & the cab & haven't changed the tubes in about 6 months. for the record the tubes are jj 636's. has anyone ever heard of this?!?
thanks for helping.
